ABSTRACT:
A quick change tool holder is provided for cutter inserts on machine tools which comprises a housing which is adapted to receive and conform to the shape of a cutter insert. A pivoting arm is mounted in the insert housing and rotates about a pivot therein. The pivoting arm has a clamp portion extending from the pivot to a position over a seat portion which is adapted to engage a cutter insert. In addition, the pivoting arm has an arm extending from the pivot opposite the clamp portion. Lastly, a cam is engaged by a distal end of the arm. The cam has a clamp position which forces the clamp portion to engage a cutter insert and a release position which forces the clamp portion to disengage from a cutter insert to allow thereof. The cam moves between the release position and the clamp position.
